Knitting-machine needle.

mamme-MACHINE NEEDLE.

To all whom z5 may concern:

Beit known that I, GEORGE Eerst, 'a "t citizen of the United States, residing an the city and county of Philadelphia, Statev of Pennsylvania, have inventeda-"new and useful Knitting-Machine Needle, Iof which the following is a specification'. i

lv y invention relates toa new and useful knitting machine needle having a butt a shank which extends the lower portion of the shank -an offset from the plane of the rear edge of the needle, whereby a space is provided between the inner edge of said sprin and the inner wall of the groove when t e needle is in operative position. By extending the shank slightly below the butt, a bearing point is provided so close to the butt that improper outward movement thereof is prevented.

It further consists of other novel features of construction, all as will be hereinafter fully 'set forth.

For the purpose of illustrating my invention I have shown in the accompanying drawings one form thereof which is at present preferred by me,.since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variouslyy arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumen` talities as herein shown and described.Y

Fig. 4 represents a perspective view of a portion 'of the needle showing a solid butt and a spring depending from the lower portion of the shank. Fig. '5 represents a similar view showing a butt formed by bending the material of the needle. Fig. 6 represents a view showing a formof spring, offset from the plane of the rear edge of the needle.

Similar numerals of reference indicate corresponding parts in the figures.

Referring` to the drawings 2"-I have found in practice, in the knitting machine needles wherein" the spring is in substantially the Specification of Letters Patent. 4Applieationlet'lrtay 20, 1912. Sea1`No-698-,374

lplane as 2vthe rear edge of theneedle, hat when any pressure or tension is exerted on fthe needle, Awhich sometimes occurs to cause the upper portion of the needle to move outwardly, the lower end thereof, and is 'forced against the rear wall of thelgroove in which the-needle is situated, causing abinding of the spring and preventin proper action thereof. In addition, wien the lower portion of the spring is forced-into engagement with the inner wall of the groove, itV will result in moving the butt outwardly too far, lthat is, into such a position that it touches the inner wall of the cam cylinder, which is not only injurious to the'latter but will also in cases bend the butt, so spoiling the needle and preventing proper operation of the same. My invention 1s designed to overcome this defect, as will be hereinafter setforth.

the shank 2 havpivoted latch 4, a is adaptedto cosame being provided with ing a suitable hook 3 and suitable portion of which operate with the hook.

5 designates a butt projecting from' the shank, which latter has a suitable portion extending slightly below said butt. 6 designates a spring which depends from the lower portion of said shank and which lspring is offset or cut away as at'7 starting substantially at the lower end 8 of said shank, which portion 8 forms a bearing point, all as will be hereinafter described. As'y will best be understood from F igs.` 3 and 4, it will be seen that the spring is preferably thinning the material forming the needle fand that said spring is reversely curved at 9 and l0 in -a plane transverse to that of the thickness of the needle, whereby I can provide a smooth surface for engagement with the side walls of the groove, which will prevent Scratching or injuring of the Walls thereof, which would be of disadvantage in that the needles may not be properly guided.

It will be seen more Figs. l and 2, when the needle is in operative position and resiliently held in place by the binder or spring 1l, that the rear edge formed by l particularly from of the shank bears against the inner wall of v the groove and that a space is provided between the inner edge of the spring and the said rear wall, whereby it will be understood thatr when tension or any pull is exerted on the needle, which will cause the same to move slightly outward in the groove,

as seen in Fig. 2, the lower end 8 of said shank forms a bearing point or fulcrum, so that while the spring 6 is caused to approach the rear wall of the groove, it will not come in contact therewith since the tension or power exerted on the needle will not be suticient for this purpose, so that the spring will always be free to perform its proper function., that is for proper engage: ment with the side walls of the grooves. In addition, by forming the bearing point, only slightly -below the butt, the point of leverage is so small that when the upper portion of the needle is moved slightly outward, there is comparatively no outward movement of the butt, so that it is free at all times of the inner wall of the cam cylinder and is always in proper position for operation.

1t will be understood that any suitable form of 'butt may be employed, that the needle may be of .any suitable material, and that any suitable means for offsetting the spring may be employed to accomplish the -a spring depending from the lower portion of said shank and offset from the plane o vthe rear edge thereof, at said nearing point, and curved in a plane transverse of that of the thickness of the needle.
